Gladiator Academy Season 1 Episode 9 Hydra Go Seek

While taking his recruits on a wilderness hike, Hocus finds a huge Hydra Egg and brings it back to the Academy to hatch it. When the egg cracks, Hocus asks Inertia to cook "whatever hydras eat". The creature loves Inertia's food so much that in a few hours' time, it has grown to a quite respectable size.
